In the Linux kernel, the following vulnerability has been resolved: serial: pch: Fix PCI device refcount leak in pchrequestdma As comment of pcigetslot says, it returns a pcidevice with its refcount increased. The caller must decrement the reference count by calling pcidevput. Since 'dmadev' is...

CVE-2022-50576

CVE-2022-50576 relates to the Linux kernel, addressing a refcount leak in the PCI device handling path for serial: pch. The root cause was that pci_get_slot() returns a pci_device with an incremented refcount, but pch_request_dma() failed to balance it in all exit paths. The fix adds a missing pc...
